Spraying is not a litter box problem, but rather, is a behavior to mark territory, particularly with male cats.

It is a communication system for a cat, appropriate when they are in the wild, but not so appropriate when they are living indoors and doing it on all your walls and furniture.

To prevent spraying, you may wish to consult your vet about neutering your (male) cat, and checking for possible medical causes.

You can try to get at the root cause by paying attention to the reasons he or she is spraying (yes, sometimes even females have this nasty habit).

There are a number of reasons why your normally placid puss might pee inappropriately, and even spray.

*  New pet, new family member or visitors
* Problems with another pet or household member
* Cats visiting in the yard
* Moving house, or remodeling

If any of these things are the case, they problem should resolve itself once the event is over.

Be sure to not punish your cat, even if caught in the act of spraying, as this will likely lead to more yucky spraying.

Remember that your pet is territorial, so try to keep its environment stable and secure.

If you still have a spraying cat, try some of the new generation of enzyme cleaners for urine, which basically break down the proteins and also the smell.

There is also a new Febreeze line of pet odor eliminators for those times when you need a bit more help with your household cleaning and fragrance, especially if your pet is spraying against the legs of your upholstered furniture.

There is also pet repellent, good for protecting your general area around the house from unwanted animals in your yard, but it can also affect your own cat. So be vigilant, and reassure your cat that he is number one in your house.
